In addition, terms such as "upper", "above", "lower", "below", "left", "right", and the like, as used herein, indicate spatial relative positions, and are used for convenience of description to describe one element or feature relative to another element or feature as illustrated in the figures. The term spatially relative position may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Referring to fig. 1 to 3, a refrigerator 100 according to a first embodiment of the present invention is schematically illustrated.

The refrigerator 100 includes a cabinet 10, a door 20 to open and close the cabinet 10, and a hinge assembly 30 to connect the cabinet 10 and the door 20.

The door body 20 includes a door body weight center, and the hinge assembly 30 drives the door body weight center to move toward the direction approaching the case 10 when the door body 20 is in the opening process.

The door body center is defined as the action point of gravity applied to each part of the door body 20, the door body 20 is relatively heavy, and the door body 20 is selectively provided with a bottle seat, a dispenser, an ice maker and other components, so that the weight of the door body 20 is further increased to cause the whole refrigerator 100 to have a tilting risk, and the hinge assembly 30 of the embodiment can drive the door body center to move towards a direction close to the refrigerator body 10, so that the refrigerator 100 can be effectively prevented from tilting.

Specifically, the direction of the door 20 facing the case 10 is the second direction Y, and when the door 20 is in the opening process, the door body center moves toward the case 10 toward the second direction Y, and at this time, the door body center approaches the case 10, so that the stability of the whole refrigerator 100 can be improved.

In the present embodiment, the case 10 includes the housing chamber S and the outer side 13 adjacent to the hinge assembly 30 and on the extension of the rotational path of the door 20, and the direction of the housing chamber S toward the outer side 13 is the first direction X.

When the door 20 is in the open process, the hinge assembly 30 drives the door 20 to move away from the case 10 in the first direction X.

Here, during the opening process of the door body 20, the door body 20 moves away from the case body 10 along the first direction X, that is, the door body 20 moves away from the accommodating chamber S, so that the door body 20 can be far away from the case body 10 as far as possible along the first direction X, the opening degree of the case body 10 is ensured, and the problem that drawers, racks, and the like in the case body 10 cannot be opened due to interference of the door body 20 is avoided.

It should be noted that, in the opening process of the door 20 of the present embodiment, the hinge assembly 30 simultaneously drives the door 20 to move in the first direction X and the door center to move in the direction approaching the case 10, that is, simultaneously increases the opening of the door 20 and avoids the refrigerator 100 from toppling.

In the present embodiment, the front end of the accommodation chamber S has an opening 12, and the case 10 further includes a front end surface 14 provided around the opening 12.

Here, the door seal 22 is disposed on a side surface of the door body 21 near the case 10 in a ring shape, and the side door seal 221 is the door seal disposed in the vertical direction closest to the hinge assembly 30.

When the door body 20 is in the closed state, the door seal 22 and the front face 14 are in contact with each other.

Here, the door seal 22 contacts the front end surface 14 to achieve sealing engagement between the door body 20 and the case 10, and generally, the sealing effect is improved by the pressing, magnetic attraction, or the like of the door seal 22.

When the door body 20 is in the opening process, the hinge assembly 30 drives the side door seal 221 to move in the first direction X.

Here, in the initial opening process of the door body 20, the rotation of the door body 20 drives the side door seal 221 to move in the opposite direction of the first direction X, and the hinge assembly 30 of the embodiment drives the side door seal 221 to move in the first direction X, so that the movement amount of the side door seal 221 in the opposite direction of the first direction X can be effectively reduced, thereby avoiding the side door seal 221 from obstructing the opening of the drawers, racks, etc. in the box 10.

Referring to fig. 4 and 5, in the present embodiment, the hinge assembly 30 includes a first shaft body 311, a first groove body 321, a second shaft body 312 and a second groove body 322, wherein the first shaft body 311 is located in one of the case 10 and the door 20, the first groove body 321 is located in the other of the case 10 and the door 20, the second shaft body 312 is located in one of the case 10 and the door 20, and the second groove body 322 is located in the other of the case 10 and the door 20.
